Title: Preparation of linea, unsubstituted quinacridone pigments of the .beta.-phase
Inventor: URBAN MANFRED
IPC: C09K23/32
Filed: 1994-11-24
Abstract: Preparation of linear, unsubstituted quinacridone pig-ments of the .beta.-phase linear,  unsubstituted  quinacridone  pigments  of  the .beta.-phase can be produced in an environmentally friendly manner by a)   cyclizing 2,5-dianilinoterephthalic acid in poly-phosphoric acid or a polyphosphoric ester to the quinacridone, b)   then hydrolyzing the quinacridone with water at a temperature of at least 40°C, preferably at from 60 to 100°C, to obtain a finely divided quinacridone pigment crude which is predominantly in the .alpha.-phase, c)   then optionally wet grinding the finely divided quinacridone pigment crude from b)  (pre-pigment), and d)   then heating the crude pigment from b) or the pre-pigment from c)  to a temperature between 120 and 200°C in the presence of from 0.1 to 1.5 times the amount of an inorganic base, based on the weight of the  crude  pigment,  in  an  inert  liquid  medium (solvent finish).            To improve the depth and hue of the color, an oxidative treatment with a peroxodisulfate can be carried out subsequently.

Title: Method for removing alkaline sulfate scale
Inventor: MORRIS RICHARD L
IPC: C02F1/46
Filed: 1993-06-02
Abstract: The present invention relates to the use of low frequency sonic energy in the sonic frequency range for enhancing the disso-lution of alkaline earth metal scales using a scale-removing solvent comprising an aqueous alkaline solution having a pH of about 8 to about 14 and containing EDTA or DTPA and a catalyst or synergist, preferably an oxalate anion. When the scale-rem-oving solvent is contacted with a surface containing a scale deposit while simultaneously transmitting low frequency sonic energy through the solvent, substantially more scale is dissolved at a faster rate than previously possible. The frequency of the sonic ener-gy is within the range of 1.5 to 6.5 kHz and preferably 1.5 kHz.

Title: Exhaust Gas Filter
Inventor: DASGUPTA SANKAR
IPC: F01N7/00
Filed: 1995-06-07
Abstract: An  electrically  conducting  ceramic  composition  is described which can be utilized in an exhaust gas filter. The ceramic composition is compacted into discs or ceramic plates,  are  subsequently  fired  or  sintered  and  then equipped with electrodes.  Electrode leads are attached to the sintered filter discs or plates bearing electrodes which are subsequently connected to a power source.

Title: Rapid coliform detection system
Inventor: BERG JAMES D
IPC: C12Q1/04
Filed: 1994-03-11
Abstract: A rapid presence-absence method for determining if fecal coliform cells are present is a sample. Portions of the original sample are filtered and retained upon microporous filters which are placed in incubation containers having an actuating medium containing a fluorogenic substrate. The samples are incubated for predetermined durations of from about twenty minutes to six hours. After adjusting the pH is adjusted to an alkaline level, the containers are irradiated and the fluorescent light emitted is measured. The measured values ale adjusted for background fluorescence  and corrected for extraneous sources of fluorescence.  It is concluded that fecal coliform cells are present in the original sample (i.e., at least one fecal coliform cell per 100 milliliters) when the corrected fluorescence values are positive meet certain predetermined criteria.

Patent CA-2161608-A1 (CA)
Title: Current ratio circuit for multi-color imaging
Inventor: STANDLEY DAVID L
IPC: G01R19/10
Filed: 1995-10-27
Abstract: An electronic circuit extracts a ratio of currents from two sources and provides an output that is a function of the current ratio. An embodiment of the circuit includes a source current that may be provided by a blue-green photodetector and a sinking current that may be provided by a red photodetector. The source current feeds the input of a current splitter formed by a pair of PFETs. A portion of the source current is fed from the current splitter to a current ratio extractor implemented in CMOS. The remaining portion of the current from the current splitter is fed to a node shared with the sinking current and a second input to the current ratio extractor. The current ratio extractor produces an output voltage that is a function of the ratio of the photodiode currents and is substantially independent of the total current. The output voltage provides color information that may be used in low-cost machine vision systems for tasks such as sorting objects based on color or detecting object boundaries while rejecting shadows and reflective glints.

Patent CA-2167324-A1 (CA)
Title: Modular Sticky Food Dispenser
Inventor: KERN FRANCOIS
IPC: A47F1/03
Filed: 1996-01-16
Abstract: A relatively hygienic dispenser is provided for dispensing particulate matter such as bulk foods, gum drops or even hardware such as nuts and bolts. A dispenser mechanism is attached to a storage bin or receptacle. The material, typically food or sticky candy, falls toward dispenser module due to gravity. The dispenser has a four sided roughly rectangular, variable geometry passageway. Two opposed sides of the passageway are rigid, and the other two opposed sides are flexible. A scoop is pivotally mounted to the two rigid walls and extends across the passageway between them. The two lobed scoop accepts material from the receptacle, is turned either clockwise or counter-clockwise, and discharges material, presumably to a waiting container.  The scoop turns between, and in contact with, the two spring-loaded sides, or skirts, and two flexible scraper walls. The scrapers discourage materials from sticking to the outside of the scoop, and the flexible skirts press close to the sides of the scoop as it is turned, limiting flow, yet may flex to discourage crushing or shearing of gummy particles. This permits control of the rate of flow of bulk food materials in a relatively hygienic manner.

Title: Multimedia collaboration system
Inventor: LUDWIG LESTER F
IPC: G06F13/00
Filed: 1994-10-03
Abstract: A collaboration system that integrates separate real-time and asynchronous networks - the former for real-time audio and video, and the latter for control signals and textual, graphical and other data - in a manner which closely approximates the experience of face-to-face collaboration. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments.  It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations (12) and their interconnecting LANs (10) and WANs (15). In the case of a plurality of geographically dispersed LANs (10) interconnected by a WAN (15), the demands made on the WAN are significantly reduced by employing multi-hopping techniques, including avoiding the unnecessary decompression of date at intermediate hops, as well as video mosaicing and cut-and-paste technology.
